Microsoft updates causing system crash

[rhik1984]

I downloaded some updates from MS update yesterday and by the evening the entire laptop was running slow, freezing frequently and at last blue screen error appeared. It didnt automatically restart after that but froze. Tried manual restart but it started freezing at boot. Tried to go to safe mode screen at boot but it frooze there too. AT last gave up and left it and when I returned, it had restarted in normal mode. Tried system restore, but they all failed. System running now, but very slow. Ran Norton 360 but nada! Please advice. Thanks

You need to perform a factory restore if you can

That would make me lose all data!

Back up that data before things get any worse
